Weisberg argued that the problems of colourism the way they existed after Cézanne have been exhausted and that the color unsaturated by semi-color carried very little information: any coloristic complexity is the result of the pigment differentiation. In 1960, Weisberg created a table of the major types of coloristic perception, their signs and structures. Weisberg art tries to find the synchronicity between semitone, composition, and drawing.
Most of his canvasses are scattered among various private collections.
